Objective To investigate the therapeutic effects of rhein on experimental diabetic nephropathy in rats. Methods Rat model of diabetic mellitus was established by interperitoneal injection of streptozotocin (50 mg/kg) . Renal damages and changes of endothelin (ET) in urine and renal tissues were observed at 12 weeks after the induction of diabetic mellitus and after treatment with rhein (70 mg/kg). Results Compared with the normal rats, at 12 weeks after hyperglycemia, diabetic rats had decreased renal weight/body weight(RW/BW), significantly increased mean glomerular plane area (MGPA), mean glomerular volume (MGV), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), and 24 hour urinary protein excretion (UPE) ( P

Objective To investigate the association adiponectin gene polymorphism with primary macroangiopathy in diabetes mellitus. Methods Type 2 diabetes mellitus (T2DM) patients were included, 56 patients complicated with atherosclerosis (AS) and 120 non-AS group. We evaluated their Gly15Gly polymorphism of adiponectin gene by PCR restriction fragment length polymorphism (PCR-RFLP). Results The AS patients were more likely to have GG genotype than the non-AS patients (25.0% vs 6.2%, P

Objective To investigate the polymorphism of peroxisome proliferator-activated receptors-?2(PPAR-?2) and its association with obesity in Chinese population.Methods According to BMI,89 subjects who are in normal body weight range and 116 overweighted and obese subjects were included in this study.Their Pro12Ala mutation in the PPAR-?2 gene was detected by PCR restriction fragment length polymorphism.Results Allele frequency of Ala mutation of PPAR-?2 in overweighted and obese subjects(qA=11.64%) was significantly higher than that of normal body weight group(qA=5.06%,P

Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.
